Description
An inline housed, pilot operated, hydraulic check valve for use as a blocking or
load holding device.
V (valve)
P (pilot)
Operation
The RVS08A allows flow from port V to port C, while normally blocking flow in the
opposite direction. Flow will be allowed from C to V when pressure is applied at
pilot port P.
The check is spring biased at 30 psi to assure holding in no load conditions. A
sealed pilot piston option with check spring bias of 70 psi is available.
Features
• Hardened closing element in a check valve to ensure extended service life
and low leakage
• Multiple bias spring options for back pressure application flexibility
• Optional sealed pilot piston
• Check section serviceable as a cartridge
• All external surfaces zinc-plated
• Aluminum and steel inline housing
